jQuery Grid Plugin - jqGrid

Thank you for the reply. But I was wondering how a grid knows when there was an error in the server scripts (php).

Let's say that I have a grid that calls a server script (php) which connects to MySQL server and returns result to the grid. And let's say that the server script could not connect to the MySQL server (or there was an SQL error or whatever…) Then, how I would like to handle those exception is for the php script to return some kind of generic error message to the grid so that the grid knows that there was an exception in the server script and displays an error message instead of showing the “Loading…” message endlessly.

I know that there is an example how to handle this with the Formedit using the callback function. However, I could not find out how to do this same type of thing for the main grid.

I would really appreciate if anyone can show me a snippet for it. Or please let me know if my questions is not clear enough.

Regards,
Daniel

Thank you Tony.

In 3.2rc, I tried loadError() function as below.

        loadError: function (xhr,st,err){
            alert("Error"+": "+st+"\\n"+xhr.responseText);
        },       

It seemed that the function loadError() worked beautifully since it caught the server error and displayed it. (Please see the screen shot: http://fact-dev.tech.northwest.....rerror.gif)

Now, the problem is that I don't know why I am getting the parsererror message.

I'm using json_encode as below.

<?php echo json_encode($responce); ?>

And the result of the function json_encode() looks OK to me. For a better readability, I reformatted the result as below:

{
    "page":"1",
    "total":1,
    "records":"6",
    "rows":[
        {"id":"2008","cell":["2008","2007-2008","No"]},
        {"id":"2007","cell":["2007","2006-2007","Yes"]},
        {"id":"2006","cell":["2006","2005-2006","No"]},
        {"id":"2005","cell":["2005","2004-2005","No"]},
        {"id":"2004","cell":["2004","2003-2004","No"]},
        {"id":"2003","cell":["2003","2002-2003","No"]}]
}

Do you have any idea why I'm getting the "parsererror" message I would really really appreicate any help on this.

My baaaad.

I realized that I was using unnecessary header information in my server script below. I commented out those and it worked perfect!

Thanks Tony!

if ( stristr($_SERVER["HTTP_ACCEPT"],"application/xhtml+xml") ) {
              header("Content-type: application/xhtml+xml;charset=utf-8");
} else {
          header("Content-type: text/xml;charset=utf-8");
}
